Ionosat-Micro
Ionosat Micro is a Ukrainian satellite mission. The head scientific organization is the Space Research Institute of NAS of Ukraine and SSA of Ukraine. General information "Ionosat-Micro" Mission realized under the National purpose scientific and technical space program of Ukraine. Particular project tasks: Project partners The history of the project Formation of the scientific objectives of the project "Ionosat - Micro" was for a long time, and conceptual provisions were first formulated in the 1990s, during the development of unrealized mission "Warning." Then, after tragic Spitakskii earthquake An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

Yuzhnoye State Design Office
Pivdenne Design Office ( uk, Державне конструкторське бюро «Південне» ім. М. К. Янгеля , lit=State design bureau "Southern", named after M. K. Yangel, translit=Derzhavne konstruktorske biuro "Pivdenne" im. M. K. Yanhelia), located in Dnipro, Ukraine, is a designer of satellites and rockets, and formerly of Soviet intercontinental ballistic missiles (ICBMs), established by Mikhail Yangel. During Soviet times the bureau's OKB designation was OKB-586. The company is in close co-operation with the PA Pivdenmash multi-product machine-building company, also situated in Dnipro. Pivdenmash is the main manufacturer of the models developed by Pivdenne Design Office.

Geocentric Orbit
A geocentric orbit or Earth orbit involves any object orbiting Earth, such as the Moon or artificial satellites. In 1997, NASA estimated there were approximately 2,465 artificial satellite payloads orbiting Earth and 6,216 pieces of space debris as tracked by the Goddard Space Flight Center. More than 16,291 objects previously launched have undergone orbital decay and entered Earth's atmosphere. A spacecraft enters orbit when its centripetal acceleration due to gravity is less than or equal to the centrifugal acceleration due to the horizontal component of its velocity. For a low Earth orbit, this velocity is about ; by contrast, the fastest crewed airplane speed ever achieved (excluding speeds achieved by deorbiting spacecraft) was in 1967 by the North American X-15. The energy required to reach Earth orbital velocity at an altitude of is about 36 MJ/kg, which is six times the energy needed merely to climb to the corresponding altitude.

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for Episodic tremor and slip, non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sich-1M
Sich-1M () is a Ukrainian spacecraft, an artificial satellite of Earth, constructed for remote sensing of Earth. Developed by Yuzhnoye Design Office and manufactured by Yuzhmash. Sich-1M was launched on December 24, 2004, at 13:20 from the Plesetsk cosmodrome (Russia) using the Cyclone-3 launch vehicle together with MK-1TS microsatellite. Both satellites placed into incorrect orbits due to premature third stage cutoff. The satellite was in orbit until April 15, 2006. Purpose Sich-1M was designed to receive information simultaneously in the optical, infrared and microwave ranges. The complex of research equipment installed on the spacecraft allowed to study the atmosphere of Earth and the World Ocean, monitoring the hydrological and ice conditions, vegetation and soil cover of the land, etc. See also * Space program of Ukraine * 2004 in spaceflight This article outlines notable events occurring in 2004 in spaceflight Spaceflight (or space flight) is an application ...
